Description
See it in action
Official LiftMaster look at the Security+ 3.0 garage door opener lineup — quiet drives, battery backup, cameras, and myQ smart control.
Why homeowners upgrade
Power outage protection
Storms happen. With built-in battery backup on equipped openers, you can still open and close when the grid drops.
Smoother DC motor
A modern DC motor is smoother than aging AC units. We will recommend belt when the garage shares a wall with living space, or chain when the door needs extra muscle.
